SPECIFICATION forming part of Letters Patent No. 309,459, dated December 16, 1884,

Application filed July i273, 1884; (X model.)

To all whom it may concern:

Be it known that I, llIILLARD l. HANS may, of Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvementsin Metallic Roofing; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked. thereon.

In the accompanying drawings, Figure 1 is a plan view of one of the roofing-sheets. Fig. 2 is a sectional view of the same, taken on the line as, Fig. 1. Fig. 3 is a view of a section of roofing constructed in accordance with my invention; and Fig. :4, is a section on the line wi s- My invention has for its object to provide an improved metallic roofing material which shall serve as a substitute for shingles or slate. I propose to furnish the said material in squares of sheet metal formed and adapted to be applied substantially as I will .now proceed to describe. Each square or sheet is formed near its upper edges with raised corrugations or ribs corrugations or ribs 7), branching out from the main corrugations a. llrom the uppermost corner of the sheet to a point, 0, toward the middle is formed a recess or depression, (1, constituting a channel. The center 0 of the sheet is raised, as shown in Fig. 1, and the body of the sheet at the points ffff is also raised, so as to leave channels 1 g 1/ between said raised portions f and the central raised portion, 0. The two upper edges, h h, of the sheets are slightly turned up,-as shown in l5i 1, while the two lower edges, of the same are turned down, as also shown in the same figure. A slit, 121, is formed in one of the lower edges of the sheet, as show-n. The sheets thus formed are fitted together by lapping the lower righthand edge of one sheet, A, upon the upper left-hand edge of the sheet 13 below to the right, the lower portion of the upper left-hand edge of saidlast-mentioned sheet being caused to take into the slot K/of the first-mentioned sheet, as shown in Fig. 3, while the lowcrlefthand edge of the sheet A, first referred to, is caused to lap the upper right-hand edge of the sheet 0 below to the left, all as shown in Fig. 3. It will be noticed that the channels formed between the corrugations b are so shaped as to tend to deflect water laterally to the right and left of the center of each square, while the form and disposition of the raised portions 6 f f f f tend to deflect the water from the interlocked corner G of the sheets, and the raised channels (I also serve to conduct away .the water from the said interlocked corners.

In applying the roofing the upper edges of the uppermost row of sheets are turned down close to the sheathing and covered and protected by a suitable strip.

To attach the sheets to the sheathing any suitable form of nails is employed, being driven through that portion of the upper edges of the sheets lying outside the corrugations ac.

The sheets may be ibrmed into the described shape at a single operation by compression in dies or otherwise, as may be preferredl.

A roof constructed according to my invention is perfectly tight, readily contracts and expands under dil'terence in temperature, and costs much less than an ordinary tin roof, be

cause less time and skill is required in laying it and no solder is needed for the joints. a a, and also with. downwardly-inclined raised The various raised portions and corrugations impressed upon the sheets and squares not only perform the mechanical function ascribed to them and give stiffness and strength, but give an ornamental appearance to the roof, as shown in Fig.

Having thus described my invention, what I claim as new is- 1. The herein -described metallic roofingsheet, consisting of a sheet of metal formed with the main corrugations a and lateral corrugations Z) arranged along the upper edge of the sheet, substantially as described.

2. The roofing-sheet provided with the corrugations a 6 along its upper edge and with recess or channel (I, substantially as described.

The roofing sheet having the central raised portion, 0, and the other raised portions, ffff, and having the channels 9 between said raised portions, substantially as described.

4-. The herein-described roofing-sheet, having its upper edges turned up and its lower edges turned down, and provided with a slot, K, in one of its lower edges, substantially as described.

5. The roofing-sheet herein described, haw

ing the upturned upper edge and. the downturned lower edge, the slot Kin one of thelower edges, and the corrugations a 1), arranged along the upper edges, substantially as described.

6. The roofing-sheet having the corrugations a I) along its upper edges, the channel (1 at its I upper corner, the raised portions e ffff, and

the downturned lower edges, one of which is provided with the slot K.
